Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 356,143,151, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 356,143,151 | |
| -1 | -356,143,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 356,143,151.
Example:
1 x 356,143,151 = 356,143,151
and
-1 x -356,143,151 = 356,143,151
Notice both answers equal 356,143,151
With that explanation out of the way, let's continue. Next, we take the number 356,143,151 and divide it by 2:
356,143,151 ÷ 2 = 178,071,575.5
If the quotient is a whole number, then 2 and 178,071,575.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 356,143,151 | |
| -1 | -356,143,151 |
Now, we try dividing 356,143,151 by 3:
356,143,151 ÷ 3 = 118,714,383.6667
If the quotient is a whole number, then 3 and 118,714,383.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 356,143,151 | |
| -1 | -356,143,151 |
Let's try dividing by 4:
356,143,151 ÷ 4 = 89,035,787.75
If the quotient is a whole number, then 4 and 89,035,787.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 356,143,151 | |
| -1 | 356,143,151 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 1,109 | 3,529 | 7,763 | 14,417 | 24,703 | 45,877 | 100,919 | 321,139 | 3,913,661 | 27,395,627 | 50,877,593 | 356,143,151 |
| -1 | -7 | -13 | -91 | -1,109 | -3,529 | -7,763 | -14,417 | -24,703 | -45,877 | -100,919 | -321,139 | -3,913,661 | -27,395,627 | -50,877,593 | -356,143,151 |
